Answer: x = 3.2 + 0.6y

Step-by-step explanation: Simplifying

5x + -3y = 16

Solving

5x + -3y = 16

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3y' to each side of the equation.

5x + -3y + 3y = 16 + 3y

Combine like terms: -3y + 3y = 0

5x + 0 = 16 + 3y

5x = 16 + 3y

Divide each side by '5'.

x = 3.2 + 0.6y

Simplifying

x = 3.2 + 0.6y

Answer:

x=10

Step-by-step explanation:

Interior Angle sum of a triangle is 180. So the angle measures are 57, 4x+4, and 7x+9. You can make an equation of 11x+70=180 by adding the angle measures together. Subtract 70 from both sides, so 11x= 110. x=10.

Answer:

Answer:

Let "b" be the total bill before the tip.

The tip was 18% of the bill, or 0.18 * b.

The tip was also $4.50, so we can set up the equation 0.18b = $4.50.

Solving for b, we get:

0.18b = $4.50

b = $4.50 / 0.18

b = $25

Therefore, Sierra's total bill before the tip was $25.

Can be determined by the inverse tangent of the shadow length divided by the height of the tree. With a shadow length of 130 ft and a tree height of 92 ft, the angle of elevation of the sun is approximately 55.55°.

The height of the tree represents one side of the triangle, and the length of the shadow represents the corresponding side of a similar triangle formed by the tree and its shadow.

tan(angle of elevation) = height of tree / length of shadow

Substituting the given values, we have:

tan(angle of elevation) = 92 ft / 130 ft

To find the angle of elevation, we can take the inverse tangent (arctan) of both sides:

angle of elevation = arctan(92 ft / 130 ft)

angle of elevation ≈ 55.55°

Therefore, the angle of elevation of the sun is approximately 55.55°.

The value of angle x is 36°

Angles on a straight line relate to the sum of angles that can be arranged together so that they form a straight line.

The sum of angles on a straight line is 180° . therefore if angles on a straight line are A, B, C

A + B + C = 180°

Similarly since the angles on the line are all x, then,

x+x +x +x + x = 180°

5x = 180

divide both sides by 5

x = 180/5

x = 36

This means the value of each angle is 36°

The probability that it will be a king or a diamond is 4/13

What is probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Here, we have

There are 52 cards, of which 4 are kings.

There are 52 cards, of which 13 are diamonds.

But there are only 3 cards that are kings which are not diamonds, and only 12 cards that are diamonds but not kings, there’s one card that is both a king and a diamond.

So, there are 3/52+12/52=15/52 chances of drawing a card that is king or diamond but not both.

There are 3/52+12/52+1/52=16/52 chances of drawing a card that is king or diamond or both.

Hence, the probability that it will be a king or a diamond is 4/13.

The equation for the least-squares regression line for the given data and the average chance of admission for a student who scores a 305 on the GRE are options b) 51% (or 0.51).

To find the equation for the least-squares regression line, we need to first calculate the slope and y-intercept. Let x be the predictor variable (GRE score) and y be the response variable (admission chance). Then, we have:

n = 10 (number of data points)

Σx = 3100

Σy = 52.1

Σxy = 161750

Σx^2 = 96100

Σy^2 = 24.71

The slope, b, can be calculated as:

b = (nΣxy - ΣxΣy) / (nΣx^2 - Σx^2)

= (10(161750) - (3100)(52.1)) / (10(96100) - 3100^2)

= 0.0644

The y-intercept, a, can be calculated as:

a = (Σy - bΣx) / n

= (52.1 - (0.0644)(3100)) / 10

= 0.336

Therefore, the equation for the least-squares regression line is:

y = 0.0644x + 0.336

To find the average chance of admission for a student who scores a 305 on the GRE, we simply substitute x = 305 into the equation and solve for y:

y = 0.0644(305) + 0.336

= 0.5136

So the average chance of admission for a student who scores a 305 on the GRE is b) 51% (or 0.51).

The amount of total cost at q* is 1.

To determine the production level that minimizes total cost, we need to find the value of q (production level) at which the derivative of the total cost function TC(q) is equal to zero. Let's begin by finding the derivative of TC(q):

TC(q) = 10 - 6q + q^2

To find the minimum point, we differentiate TC(q) with respect to q:

d(TC(q))/dq = -6 + 2q

Setting the derivative equal to zero and solving for q:

-6 + 2q = 0

2q = 6

q = 3

So the production level q* that minimizes the total cost is 3.

To find the amount of total cost at q*, we substitute q = 3 into the total cost function TC(q):

TC(q*) = 10 - 6(3) + (3)^2

TC(q*) = 10 - 18 + 9

TC(q*) = 1

The preliminary sample size is undefined since the projected misstatement is zero.

In determining the appropriate sample size for testing inventory valuation using MUS, the following steps are taken;

Given that the population has 2,620 inventory items valued at $12,625,000 and the tolerable misstatement is $500,000 at a 10% ARIA, we can calculate the preliminary sample size using the formula;

Preliminary sample size = (Confidence Factor2 × Tolerable Misstatement)/Projected misstatement.

Considering that no misstatements are expected in the population, the projected misstatement will be zero.

Thus; the Preliminary sample size = (2.31 × 500,000)/0. Preliminary sample size = (2.31 × ∞) / 0. The preliminary sample size is undefined.

In conclusion, the preliminary sample size is undefined since the projected misstatement is zero.

Since dim(U) = 4, which means the dimension of the vector space U is 4, it implies that any element y in U can be represented as the root of a rational polynomial P(x) = Q[x] with a degree less than or equal to 4.

The vector space U is defined as U = {a + b√2 + c√3 + d√6 | a, b, c, d ∈ Q}, where Q represents the field of rational numbers. We are given that the dimension of U is 4, which means that there exist four linearly independent vectors that span the space U.

Since every element y in U can be expressed as a linear combination of these linearly independent vectors, we can represent y as y = a + b√2 + c√3 + d√6, where a, b, c, d are rational numbers.

Now, consider constructing a rational polynomial P(x) = Q[x] such that P(y) = 0. Since y belongs to U, it can be written as a linear combination of the basis vectors of U. By substituting y into P(x), we obtain P(y) = P(a + b√2 + c√3 + d√6) = 0.

By utilizing the properties of polynomials, we can determine that the polynomial P(x) has a degree less than or equal to 4. This is because the dimension of U is 4, and any polynomial of higher degree would result in a linearly dependent set of vectors in U.

Therefore, every element y in U must be the root of some rational polynomial P(x) = Q[x] with a degree less than or equal to 4.
